I was also under the impression that there was a little difference in string length (on a D/G) between the high D string and the low D. Example: High D chanterelle has, open, a length of 34.6 cm. The D octave tangent is, without adaptation to left or right, at exactly 17.3 cm. If I do the same for the low D, the D octave tangent needs a lot of adapting.
the moveable saddle (and frets) are there to compensate different behavior of strings from differing flexibility. A stiffer string for example does not vibrate as close to the notch as a more flexible so it needs a longer distance between bridge and saddle or fret for the same pitch. The flexibility changes for example with diameter and materials.
Your aim in finding the perfect saddle position is to keep the tighter keys frets - from the octave upwards - even since there is only few space for bending them. Instead of moving the frets you move the saddle. But moving the saddle moves all the ideal positions for all frets. So, this adjustment is a balance between the angles of the frets in the upper and lower parts of the string.
